A 31-year-old man who developed red-tinted vision said his symptoms started after he ingested a high dose of liquid erectile dysfunction medication that he purchased online. In a case study published in the journal Retinal Cases, the unidentified patient was complaining of a red tint in both eyes and multicolored flashes for two days.
The man, who took more than the recommended 50 mg dose of the sildenafil citrate, which is commonly sold under the brand name Viagra, was diagnosed with persistent retinal toxicity, and found to have damaged his retina. According to Newsweek, the patient has continued to experience red-tinted vision despite receiving various treatments for over a year.
The researchers concluded that his condition was caused by an overdose of the medication.
A few questions... Why is a 31 y.o. taking Viagra? Can't he read directions? Did his erection last longer than 4 hours?
